After uploading a backed-up game onto my box, I rebooted and only the xbox live startup screen is present. I can't load a CD or do anything. I have an mod chip installed (cheapmod?) and was wondering if there was a way to bypass my HD or whatever to run a CD that could reload my bios or whatever I would need to get my XBox running again. I'd hate to buy a new one, and I want to play Halo very badly. Please help!!
